Improving Solr's Update Chain, Jan Høydahl, Cominvent AS, Eurocon 2011 from Lucene Revolution on Vimeo.

Solr features a little known internal document processing pipeline called the UpdateRequestProcesssorChain or simply the UpdateChain.

In this talk we'll discuss the importance of document processing, when the UpdateChain works well and what limitations it's got. We'll then go on to propose a range of possible improvements.

Topics include:

  • Examples of use with demo
  • How to write your own UpdateProcessor, best practices
  • Example: Tika as an UpdateProcessor
  • A vision for future improvements
